Valentine's Day is tomorrow, and the Kidd Kraddick in the Morning show is in the mood for love! What better way to get into a sexy mindset than a little "Bump n' Grind" by R. Kelly showdown?

J-Si challenged Big Al to a singing competition featuring the song. And there ain't nothing wrong with a little bump n' grind!

Big Al brings soul to his rendition, but J-Si easily has more passion.

Who do you think sings "Bump n' Grind" better? Let us know in the comments!
